Project Summary

Swarm robotics is an approach to collective robotics that takes inspiration from the self-organized behaviors of social animals. Through simple rules and local interactions, swarm robotics aims at designing robust, scalable and flexible collective behaviors for the coordination of large numbers of robots. The main focus of the project is  ideas and concepts that contribute to the advancement of swarm robotics as an engineering field and that could be relevant to tackle real-world applications. 

Project Objectives

As an emerging research area, the swarm intelligence has attracted many researchers’ attention since the concept was proposed in 1980s. It has now become an interdisciplinary frontier and focus of many disciplines including artificial intelligence, economics, sociology, biology, etc. It has been observed a long time ago that some species survive in the cruel nature taking the advantage of the power of swarms, rather than the wisdom of individuals

Advantages of robot collectives shown in:

environmental exploration

materials transport

coordinated sensing –

collective cooperates to provide maximal sensor coverage of moving target.

robot soccer search and rescue

The objectives of this project is to learn major functions of robots in the swarm: 

1) Communication between swarm bots: The Robots in the swarm exchange the information with each other and propagate the information to the whole swarm through autonomous behaviors resulting in the swarm-level cooperation.

2) Avoid collision between swarm robots

3) Synchronization between bots

Project Implementation Method

Swarm robots use a coordinated shared intelligence to operate as a group and work in coordination. These applications require the use of wireless communication for fast and efficient communications. Our system uses this concept to apply it in a pair of swarm robots that are based on a master slave relationship. The master robot is integrated with IR sensors to perform a specific task. In this case the master has a circuitry that consists of an integrated IR sensing circuit controller by a microcontroller circuit that is used to follow a line. The IR sensors are used to sense the line drawn and follow using reflected light principle of operation. While performing its operation the controller also transmits the movement commands to the slave robot using Rf communication. The slave robot consists of an microcontroller circuit integrated with similar motorized robotic body as the master. It receives the commands sent by master and operates the motors in order to achieve motion as per commands sent by the master. 

Benefits of the Project

 The swarm is distributed and de-centralized, and the system shows high efficiency, parallelism, scalability and robustness.

The potential applications of swarm robotics include the tasks that demand the miniaturization, like distributed sensing tasks in micro machinery or the human body. On the other hand, the swarm robotics can be suited to the tasks that demand the cheap designs, such as mining task or agricultural foraging task. The swarm robotics can be also involved in the tasks that require large space and time cost, and are dangerous to the human being or the robots themselves, such as post-disaster relief, target searching, military applications, etc.

Technical Details of Final Deliverable

The main scientific objective of the Swarm-bots project is to study and aim at controlling the s-bots assemble into structures.Swarm-bot is made of master and slave whereby the master controls the slave using RF module to carry out the desired task.

One Swarm-bot is composed of number of similar robots, called s-bots, physically interconnected. The Swarm-bot is provided with self-assembling capabilities. This project introduces the Swarm-bot with a master and two slaves and describes its application as transportation bot.

The robots in the swarm should have some basic functions-

1) Communication between swarm bots: The Robots in the swarm exchange the information with each other and propagate the information to the whole swarm through autonomous behaviors resulting in the swarm-level cooperation.

2) Avoid collision between swarm robots

3) Synchronization between bots
